Answer: 6.6
You can divide 66 by 10 to get the answer. To do it quickly, just move the decimal point in 66 to the left one spot
Using the equation of the test statistic, it is found that with an increased sample size, the test statistic would decrease and the p-value would increase.
<h3>How to find the p-value of a test?</h3>
It depends on the test statistic z, as follows.
- For a left-tailed test, it is the area under the normal curve to the left of z, which is the <u>p-value of z</u>.
- For a right-tailed test, it is the area under the normal curve to the right of z, which is <u>1 subtracted by the p-value of z</u>.
- For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is <u>2 multiplied by 1 subtracted by the p-value of z</u>.
In all cases, a higher test statistic leads to a lower p-value, and vice-versa.
<h3>What is the equation for the test statistic?</h3>
The equation is given by:
The parameters are:
- is the sample mean.
- is the tested value.
- s is the standard deviation.
From this, it is taken that if the sample size was increased with all other parameters remaining the same, the test statistic would decrease, and the p-value would increase.

Scientific notation is a way to write compactly numbers with lots of digits, either because they're very large (like 2393490000000000000000000), or very small (like 0.0000000000356).
We use powers of ten to describe all those leading/trailing zeros, so that we con concentrate on the significat digits alone.
In your case, the "important" part of the number is composed by the digits 6 and 1, all the other digits are zero. But how many zeroes? Well, let's do the computation.
Every power of 10, is written as one zero followed by n zeroes, so we have
Multiplying a number by means to shift the decimal point to the right and/or add trailing zeroes n times. So, we have to repeat this process six times. We shift the decimal point to the right one position, and then add the five remaning zeroes. The result is thus
Let
p-------->total paintings that Sergio has in his art collection
step 1
<u>Find the number of paintings that each collectors will donate</u>
Divide the total paintings that the collectors will donate by the number of total collectors
=(48/12)=4 painting
<u>Find the numbers of paintings will sergio have in his art collection after his donation</u>
p-4
therefore
<u>the answer is</u>
(p-4)
Answer:
Jason sold 22/51 of the total sales and Trinity sold 29/51 of the total sales.
Step-by-step explanation:
Assuming that Trinity and Jason are the only ones selling ads, we much combine their sales to find the total sales. Then we can set up a proportion for each individual and reduce their fraction.
If Trinity sold $2030 worth of ads and Jason sold $1540 then
2030 + 1540 = 3,570
Trinity and Jason have a combined total of $3,570 is sales.
Trinity's fraction then becomes
2030 / 3570
Which can be reduced to
29 / 51
Jason's fraction of sales is then
1540 / 3570
Which reduces to
22 / 51
